Roll-off in Sigmas is funny in a way that it is, for me at least, sounds very natural and speaker like. Overall presentation remind me of very HQ planar ribbon system. Awesome headphones that sound very lifelike and big.
Great review. I have to ask you this tough, how do this fair with very fast and aggressive music?
For me ortho headphone were primarily rock, metal and hard-core phones. I really like my stats and AMT for all and any kind of music with one exception, I was using YH-100 and my other ortho phones for very fast, loud, aggressive and complex music with a lot of stuff going, they would not get confused and had a kick to them that even the best stat did not deliver.
P.S. Can I copy your review to Wikiphonia?
I used to love Lala when it was just a CD trading site. They were great and also had a good CD store that had very competitive prices. When they moved to this music web-based listen nonsense I stopped using them. I guess I am just old-school.
Bought a few cheap Vinyls, a bit scratchy and dusty but play fine and all are original first issues is seems.

Very dark Swiss progressive band with strange instrumentation: percussion, drums, gongs, keyboards, pedal-bass, saxophones, flute, clarinet, and Peter Hammill like vocal delivery.
